3 Claims.

In the production of wire it is customary to utilize machines comprising a plurality of dies arranged in tandem, the wire being drawn through the dies by means of a series of blocks rotatable about vertical axes. The dies are usually mounted at one side ofthe machine so that they are readily accessible to the operator. In order to facilitate subsequent operations on the wire it is desirable that the coils delivered by the machines be all of the same hand, and it has accordingly become the standard practice in the industry to rotate all of the blocks in a counter-clockwise direction. An operator who has charge of two of these machines is compelled to pass around the end of one machine in order to reach the dies on the other machine. This is inconvenient and wasteful of the operator's time, rendering it difficult for him to obtain the maximum production from the machines.

It is accordingly the main object of the invention to provide a pair of wire drawing machines of the multiple die type which will deliver coils of the same hand, and which are so constructed and arranged as to facilitate the work of the operator.

It is a further object of the invention to provide a series of wire drawing machines'of the multiple die type which are so constructed and arranged as to occupy a minimum of fioor space and deliver a maximum production of coils identical in hand, while facimiating the attendance of the machines on the part of the operating crew.

With these and other objects in View, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended herein.

Referring to the drawing illustrating one embodiment of the invention and in which like reference numerals indicate like parts,

Fig. l is a plan view of a series of wire drawing machines;

Fig. 2 is a section on the line 2-2 of Fig. 1; and

Fig. 3 is a section on the line 3-3 of Fig. 1.

As shown particularly in Fig. 1, I have provided a series of wire drawing machines of two slightly difi'erent constructions, which I have designated as A- machines and B machines. The A machines alternate with the B machines, and

each A machine is located closely adjacent to the B machine on one side but spaced from the B machine on the other side to provide an operating aisle l0.

Each A machine comprises a frame I I generally rectangular in plan and arranged to support a plurality of preliminary blocks [2 and a finishing block Hi. All of the blocks 12 and M are arranged to be rotated about vertical axes in a counter-clockwise direction, and for this purpose a horizontal driving shaft I5 is supported in the frame ll beneath the blocks and connected to the blocks by means of pairs of bevel gears Hi. In advance of each preliminary block l2 there is provided a roughing die I8, and in advance of the finishing block l4 there is provided a finishing die l9, these dies being supported upon the frame II. The dies l8 and ii! are all located at the side of the machine adjacent to the aisle l0, where they are readily accessible to the operator. It will be understood that the wire travels through the first of the roughing dies l8, then makes several counter-clockwise turns about the first of the preliminary blocks I2, and thereupon passes alternately through the remaining dies l8 and around the remaining blocks l2, finally passing through the finishing die H! to the finishing block l i where it is formed into a counter-clockwise coil. t

Each B machine comprises a frame 2i generally rectangular in plan and arranged to support a plurality of preliminary blocks 22 and a finishing block 26. All the preliminary blocks 22 are arranged to be rotated about vertical axes in a clockwise direction, and the finishing block 24 is arranged to be rotated about a Vertical axis in a counter-clockwise direction. For this purpose a horizontal driving shaft 25 is supported in the frame 2i beneath the blocks and connected to the blocks by means of pairs of bevel gears 26. In advance of each preliminary block 22 there is provided a roughing die 28, and in advance of the finishing block 24 there is provided a finishing die 29, these dies being supported upon the frame 2|. The roughing dies 28 are all located at the side of the machine adjacent to the aisle l0, where they are readily accessible to the operator. The finishing die 29 is shown located near the longitudinal center line of the machine, and while not so close to the aisle as the roughing dies it is nevertheless readily acces-' sible therefrom. It will be understood that the wire travels through the first of the roughing dies 28, then makes several clockwise turns about the first of the preliminary blocks 22, and thereupon passes alternately through the remaining dies 28 and around the remaining blocks 22, finally passing through the finishing die 29 to the finishing block 24 where it is formed into a counter-clockwise coil.

The general direction of travel of the wire is the same in all the machines, so that the handling of material is facilitated. The rod bundles can be delivered to the machines at one end and the bundles of drawn wire can be removed at the other end. One man can readily operate two machines, since each aisle l allows ready access to one A machine and to one B machine. All the machines produce bundles of the same hand, so that subsequent manufacturing operations are in no way hampered.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. Wire drawing apparatus comprising a pair of 2. Wire drawing apparatus comprising a plurality of machines arranged parallel to one another with alternately wide and close spacing between adjacent machines, whereby operating aisles are .provided between successive pairs of machines,

each machine having a plurality of dies arranged in tandem along the side of the machine adjacent to the corresponding aisle and. a plurality of blocks rotatable about vertical axes to draw the wire through the dies with the general direction of travel of the wire the same in all machines, the finishing blocks on all machines being arranged to rotate in the same direction to produce coils identical in hand;

3. Wire drawing apparatus comprising a pair of machines arranged parallel to one another and separatedby an operating aisle,each machine having a plurality of dies arranged in tandem and readily accessible from the aisle, each machine also having a plurality of blocks rotatable about vertical axes to draw the wire through the dies with the general direction of travel of the wire the same in both machines, means to rotate all of the blocks on the first machine and the finishing block on the second machine in the same direction, and means to rotate the remaining blocks on the second machine in the opposite direction.
